from flying sparks, fumes hazardous to health, noise exposure, possible haz-
ard due to grid current or process current, etc.),
-Provide suitable protective equipment, or
-Construct suitable protective walls and curtains.
Data regarding
Noise Emission
Values
The device produces a maximum noise level of <80 dB(A) (ref. 1pW) when idling
and in the cooling phase following operation in relation to the maximum permit-
ted operating point at standard loading in accordance with EN 60974-1.
8
A work station-specific emission value cannot be specified because this value de-
pends on the process and the environmental conditions. It depends on differing
parameters, such as the power range, the component geometry, the material, the
resonance properties of the workpiece, the work station environment, and many
other factors.
Danger from
Toxic Gases and
Vapors
The fumes produced during plasma surface treatment contain toxic gases and
vapors.
The fumes produced contain substances that may cause birth defects and can-
cer in some circumstances.
Use at-source extraction source and a room extraction system.
If possible, use integrated extraction devices.
The operator of the plasma system is obliged to maintain the values for the max-
imum allowable concentrations (MAC).
-Ensure that there is sufficient fresh air!
-Arrange the extraction capacity so that at least 3 times the gas used can be
extracted per plasma torch.
Keep your head out of the fumes and gases.
Take the following precautionary measures for fumes and harmful gases:
-Do not breathe them in
-Extract them from the work area using appropriate equipment.
Use breathing apparatus with air supply if there is insufficient ventilation.
When no work is taking place, close the valve of the gas cylinder or the main gas
supply.
If there is uncertainty as to whether the extraction capacity is sufficient, com-
pare the measured toxic emission values against the permissible limit values.
The following components are factors that determine how toxic the fumes are:
-The materials used for the workpiece
-Electrodes
-Coatings
-Cleaning agents, degreasers, and the like
-The type and amount of component contamination
Consult the corresponding material safety data sheets and manufacturer's in-
structions for the components listed above.
Keep flammable vapors (such as solvent vapors) out of the arc radiation range.
Danger from Fire Flying sparks can cause fires and explosions.
Never perform the plasma surface treatment near flammable materials.
Flammable materials must be kept at least 11 meters (36 ft. 1.07 in.) from the
arc or protected with a certified cover.
Keep suitable, tested fire extinguishers on hand.
Sparks and pieces of hot metal may also get into surrounding areas through
small cracks and openings. Take appropriate measures to ensure that there is no
risk of injury or fire.
9
EN-US
Only ever perform the plasma surface treatment in areas at risk of fire and ex-
plosion, on sealed tanks, drums, or pipes if these have been prepared in accord-
ance with corresponding national and international standards.
Do not perform the plasma surface treatment on containers in which gases,
fuels, mineral oils, and the like are/were stored. Residues pose a risk of explosion.
Do not perform plasma surface treatments on materials or contamination which
could cause a fire when the plasma arc is operated.
Hazards from
Grid Current and
Process Current
An electric shock is life-threatening and may be deadly.
Do not touch voltage-carrying parts inside or outside the device.
Ensure suitable personal protection with dry temporary backing or cover with
sufficient insulation against the ground potential. The temporary backing or cov-
er must completely cover the entire area between the body and the ground po-
tential.
All cables and leads must be secured, undamaged, insulated, and adequately di-
mensioned. Replace loose connections and scorched, damaged, or inadequately
dimensioned cables and leads immediately.
Before every use, check power connections for secure fit by hand.

least 180° around the longitudinal axis and pretension.
Do not wrap cables or leads around your body or parts of the body.
The electrode
-never immerse it in liquids to cool it
-never touch it when the power source is switched on.
The open circuit voltage of a device may double, for example, between two
voltage-carrying electrodes. Touching the potentials of both electrodes at the
same time may be life-threatening in some cases.
Have the grid and device supply lead regularly inspected by an electrician to en-
sure that the ground conductor is functioning properly.
Only operate the device on a grid with a ground conductor and a socket with a
ground conductor contact.
Operating the device on a grid without a ground conductor and on a socket
without a ground conductor contact is considered gross negligence. The manu-
facturer accepts no liability for any damage resulting from improper use.
Use suitable equipment to ensure that the workpiece is sufficiently grounded if
necessary.
Switch off unused devices.
Before working on the device, switch off the device and remove the mains plug.

-Hang it on a gas cylinder
-Point it at or place it on a gas cylinder
Never touch a gas cylinder with an electrode.
Risk of explosion - never perform a plasma surface treatment on a compressed
gas cylinder.
Always use suitable gas cylinders for the application in question and the correct
matching accessories (controller, hoses, and fittings, etc.). Only use gas cylinders
and accessories that are in good condition.
If a valve on a gas cylinder is open, turn your face away from the outlet.
If no plasma surface treatment is being performed, close the valve of the gas cyl-
inder.
Leave the cap on the valve of the gas cylinder when the gas cylinder is not con-
nected.
Follow the manufacturer's instructions and applicable national and international
provisions for gas cylinders and accessories.
Danger due to
Escaping Gas

General
Device Concept The fully digitized and microprocessor-
controlled Acerios plasma power
source is used for Hot Active Plasma
(HAP) surface treatments on metallic
materials.
The modular design makes it easy to
upgrade the system and allows great
flexibility. The devices can be adapted
to practically any conditions.
The plasma power source has a Local-
Net interface to make it easy to con-
nect digital system add-ons. The ex-
tensive robot and system interfaces
simplify networking and control.
All key functions can be quickly viewed and adjusted.
Job Mode allows differing process parameters to be saved and retrieved and can
be used for pre-setting.
The plasma pulsed arc function with a wide frequency range provides additional
process-stabilizing options.
The Acerios plasma power source has an optimized high-frequency ignition pro-
cess for short cycle times and high repeatability.
NOTE!
The plasma surface treatment process will simply be referred to as the plasma
process in the rest of these instructions.
Operating Prin-
ciple
The central control and regulation unit of the plasma power source is coupled
with a digital signal processor. Together, the central control and regulation unit
and signal processor control the entire plasma process.
During the plasma process, the actual data is measured continuously and the
device responds immediately to any changes. Control algorithms ensure that the
desired status is maintained.
This results in:
-a precise plasma process,
-an exact degree of reproducibility for all process parameters,
-excellent surface treatment properties.
The energy yield can be individually tailored by distance and speed.
It is possible to achieve high plasma process speeds, thanks to stable and precise
arc control and the regulated supply of process gas (argon).
Another gas can be introduced via an additional gas connection, e.g. as a shield-
ing gas or as a reactive gas.
19
EN-US
Application
Areas
